Abstract: A coil spring modeling apparatus (20) includes an actuator unit (30) formed of a Stewart-platform-type parallel mechanism, a first inner load cell (41) accommodated in a first attachment member (21), a second inner load cell (42) accommodated in a second attachment member (22), and a rotation support mechanism (50). The actuator unit (30) is rotatably supported by the rotation support mechanism (50) about an axis (L 1 ). The first inner load cell (41) is arranged on the first seat adapter (27) coaxially with the rotation support mechanism (50), and detects an axial force acting on the lower spring seat (10A) and a moment. The second inner load cell (42) is arranged under the second seat adapter (28) coaxially with the rotation support mechanism (50), and detects an axial force acting on the upper spring seat (15A) and a moment.

Abstract: A coil spring modeling apparatus (20) includes a first attachment member (21) disposed on a lower spring seat (10A), a second attachment member (22) disposed on an upper spring seat (15A), an actuator unit (30) formed of a Stewart-platform-type parallel mechanism, a hydraulic pressure supply device (37), a torsion detection mechanism (40A), and a controller (70). The torsion detection mechanism (40A) is constituted of displacement gauges (40 1 -40 6 ) such as a linear variable differential transformer (LVDT). The displacement gauges (40 1 -40 6 ) are provided on hydraulic cylinders (31 1 -31 6 ), and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders (31 1 -31 6 ), respectively. The controller (70) calculates a relative torsional angle between the first attachment member (21) and the second attachment member (22) based on the detected amounts of displacement.

Abstract: An ultrasonic welding structure for pressing a horn (3) against a columnar heating target consisting of a resin (10), applying a high frequency vibration from the hone (3) to the heating target, and thereby fusion-bonding the heating target to a predetermined bonding target, wherein the bonding target includes an insertion hole for inserting the heating target, and the insertion hole of the bonding target includes a notch formed in an inner edge of the insertion hole on a side facing the resonator. The notch of the insertion hole can be formed to serve as an acceptance unit that accepts the heating target in a molten state. Alternatively, the notch of the insertion hole can be formed to serve as a stress relaxing unit that relaxes a stress generated within the bonding target by contacting with the inner edge of the insertion hole.
